after you capture palkia fly to snowpoint city and go left tell you get to acuity lakefront go in to where you can see the lake surf on the water and capture it
you find them in the three lakes in diamond, pearl, and platinum.
for pearl catch palkia the main boss to pearl an go to the lakes verity valor acuity
You can find Palkia, Uxie, Mesprit, Azelf, Giratina, Cresselia, and Regigigas
okay if you want to get palkia you have to go to mt. coronet after rescuing azelf ,mespirit, and uxie in the galactic hideout.
uxie
a gaywad
You can't capture Uxie more than once on this game, but you can own more than one Uxie if it is traded to you.
Not in Pearl and Diamond. In Platinum you can.
After you release Azelf, Uxie and Mespirit from the Team Galatic HQ, go to Lake Acuity. Surf across to the cave. Talk to Uxie to start the battle.
In Pokémon Diamond and Pearl, you only have one chance to capture Uxie. If Uxie faints or if you run away, then you will not get another chance to capture it. The answer is no.
Well, first if you set all three of them (Uxie Azelf Mespirit) free from team galacturd, you can find it again back in it's cave at lv. 50 i think..
it means mespirit,azeleaf,and uxie are connected to palkia's pearl somehow
